Benefits of technology
The invention is a liquid detergent for hand washing dishes that contains a specific type of ethoxylated anionic surfactant and a specific type of alkoxylated branched nonionic surfactant. The composition has a specific ratio of these two types of surfactants, which results in improved cleaning performance. The detergent can be used in its undiluted form when washing dishes.
Problems solved by technology
However, since natural surfactants have little or no branching, such compositions produce lower levels of suds.
Even worse, such detergent compositions have low suds-mileage.
In addition, high levels of linear anionic surfactants, such as those derived from renewable natural sources, but also linear synthetic surfactants, lead to worse stability of the resultant composition at low temperature.

examples
[0119]The composition of example 1 is the reference. The reference composition does not comprise the ethoxylated anionic surfactant of the present invention (wt % linearity below 80% and average degree of ethoxylation of less than 0.8), and does not comprise an alkoxylated branched non-ionic surfactant.[0120]Example 2 is outside the scope of the present invention. Example 2 has the anionic surfactant of the present invention, but does not contain an alkoxylated branched non-ionic surfactant. As demonstrated in the table below, such composition provides improved grease-cleaning, no improvement of the suds profile but poorer low temperature stability.[0121]Example 3 is also outside the scope of the present invention since it does not contain the specified anionic surfactant. However the composition of example 3 does contain the alkoxylated nonionic surfactant of the present invention. As demonstrated in the table below, such composition provides only limited improvement in grease-clea...

Abstract
The need for a liquid hand dishwashing detergent composition, having excellent low temperature stability and delivering good cleaning and long-lasting suds, is met by incorporating a branched, alkoxylated nonionic surfactant, in combination with ethoxylated anionic surfactants having little or no branching, into the composition. Surprisingly, such a combination also provides an excellent sudsing profile during direct application dishwashing methods.
Description
FIELD OF THE INVENTION[0001]The present invention relates to stable liquid detergent compositions for dishes, comprising low branched anionic surfactants and branched nonionic surfactants that deliver effective grease-cleaning with enduring suds.BACKGROUND OF THE INVENTION[0002]Consumers desire hand dish-washing products that deliver both long lasting grease cleaning and long lasting suds. Additionally, more and more consumers are looking for products that contain a greater proportion of ingredients that are derived from natural, renewable sources. These include liquid hand dishwashing detergent compositions containing higher levels of surfactants derived from renewable sources, and having less surfactants derived from crude oil. However, since natural surfactants have little or no branching, such compositions produce lower levels of suds. Even worse, such detergent compositions have low suds-mileage. That is, the suds endurance is less than what most consumers would like.[0003]In a...
